You could have just said, "what?" It's kind of an all-encompassing term that tends to alleviate redundancies.
I
think that they meant was that it is easier to create a believable setting in an old temple than one in prehistoric times simply because we can actually visit temples and tombs (as many of us have). Not so much with living dinosaurs (unless Lucky counts). Assuming that's what they meant, I tend to agree. In Dinosaur, there is a lot of empty space, true, but it is deliberate and, ironic as it sounds, functional. The abysmal blackness of the ride plays into people's fears of the unknown, which is appropriate considering the predicament they are in where anything can strike at any moment. It's definitely harder to suspend belief in a dinosaur setting than an ancient tomb and I thought it was handled superbly via darkness in Dinosaur. Again though, I could be completely misreading TheDecemberists.
